We have had several calls about someone getting a new iPhone 6 and now they are no longer receiving the company emails which are handled with an Exchange server. We set up the connection, and get all check marks but still won’t sync. Here is what we have found to solve it.

1. In Active Directory click on “View” and check “Users, Contacts, Groups, and Computers as containers.”
2. Next the user with the issue is now a plus sign.
3. Expand the plus sign and select “ExchangeActiveSyncDevices”.
4. Remove any entries and the person should now be able to connect.
